Posts on Twitter and Instagram from Bieber and other local artists and producers affirm that the part-time Alpharetta resident who got his start with Atlanta’s Usher and Scooter Braun is in town working with Dupri, AutoTune afficionado T-Pain and a wide assortment of other hip-hop artists.

In addition to being spotted shirtless at Vanquish (and summarily ridiculed on “TMZ Live” as “a circus act” to his fellow partiers), camera phones have captured him playing a pick-up game of hockey at Marietta Ice Center in east Cobb County and leaving tony Phipps Plaza in Buckhead after seeing the Kevin Hart/Ice Cube film “Ride Along.”

According to Bieber himself, via Twitter, he’s in his second home “building up positive energy.”
